You are working for a company that has four workers. each has their own best operating level for getting projects completed. the first worker can do 1.5 project per day. the second can do 2 projects per day. the third can do 3 projects per day. the fourth worker can do 1.5 projects per day. however, due to a lack of available computers (i. e., the bottleneck), the actual number of projects completed per day is only 2. what is the capacity utilization rate for this company?
